Abstract

An imaging system for use with a patrol car includes at least one image pick-up device, a memory device, and a controller. The controller executes instructions to store image information captured by the image pick-up device in the memory device. Various operating modes of the imaging system may be selected based in part upon the operating conditions of the patrol car. Recording and transmitting of the image information may be performed manually or automatically, depending upon the operator of the system and the conditions of the patrol car. Both the interior of the patrol car (i.e., rear seat), and the environment outside of the patrol car (i.e., to the front and rear of the vehicle), may be recorded by the image pick-up systems. Additionally, automatic control such as 360° views upon reaching a desired destination may be performed based upon the configuration of the imaging system.
